1 Claim.

1. p This invention relates to improvements. in can: vas furniture of the type sometimes referred to as lawn furniture and relates-more particularly to an anchor for removablyattaching a hamg Flexible supporting members are usually at tached in such a way that it is difiicult to remove them from. and attach them to the frame'anda flsja result they are not removed to. protect them against rain or snow or other elemental agencies and they soon deteriorate;

It is the object of this invention to produce a furniture construction in which means isi-plro- .vided for anchoring the'flexible supporting memberto the frame in such a way'that it canb'e very easly removed and replaced, and which will securely hold the supporting member in operative position.

The above and other objects that may become apparent as the description proceeds are attained by means of a construction and an arrangement of parts that will now be described in detail and for this purpose reference will, be had to the accompanying drawing in which the invention has been illustrated, and in which:

Figure l is a perspective view showing the invention applied to a hammock type reclining chair which serves as an illustration of furniture of this type; I

Figure 2 is a section, to an enlarged scale, taken on line 22, Figure 1; a

Figure 3 is a perspective view of the anchor showing the same detached from the frame member with which it is operatively associated in Figure 1;

Figure 4 is a section through a frame pipe showing a slightly modified form of anchor;

Figure 5 is a view similar to that shown in Figure 1, but shows one position of the anchor during its application and removal from the pipe; and

Figure 6 is a top plan view showing the anchor and flexible tension element operatively connected with a pipe.

The invention has been illustrated in connection with a hammock type chair as shown in Figure 1. This chair has been shown as formed from a tubular frame member bent into the desired shape and Welded so as to form a un.itary frame. The sides have been designatedb'y having a central opening I8.

reference numeral. l0 and are shown as" spaced and. substantially parallel forming an opening. The bottom has been designated by reference numeral H'. Brace members. [2 and l3 have been shown to keep the sides of the frame in properly spaced relation. The side members I I] are provided with a plurality of'spaced'apertu're's M on the outside as shown in Figure 1. Where the frame is made from pipe tube, the openings extend through the outer wall as shown" in Figure 2. It will be observed from Figure 2' that apertures 14 are on the outside of corresponding vertical diametrical planes X"X' and preferably below a horizontal diametrical plane like that indicated by Oand Y. The flexible supporting sheet has been designated by reference" numeral l5; Forthe purpose of securing the'sheet'to the frame so-that it maybe readily removed; flexible straps -6 are provided and attached to the back of the sheet by being sewed thereto or by other suitable means. In the invention as illustrated, strap I6 is made from fabric and is either double or provided at each end with a loop I l Secured to the ends of strap 11 are anchors like that shown in Figure 3. These anchors have a substantially straight shank I?! to one end of which is secured a cross bar 20. The other end of shank I9 has a portion 2| that is curved on the radius R which is substantially equal to the radius of the outer surface of frame member l0. Curved portion 2| terminates in an inwardly extending book 22 that engages in one of the openings I4 as shown in Figure 2. When pressure is exerted downwardly on strap IS in the direction of arrow 23, a force is applied to the cross bars 20 in a direction somewhat as indicated by arrows 24. This force tends to move the curved portion 2| against the outer surface of the pipes [0 forming the frame, and the greater the force the more securely the anchors hold the supporting member in position. When the supporting member 15 is to be removed, one of the anchors is disconnected by turning it slightly in a clockwise direction as indicated in Figure 5. There is, of course, some slack in member 16 at all times and this makes the removal and application of this supporting member quite easy.

In Figures 4 and 5 a slightly modified form of construction has been shown. In this construction the apertures I 4 are at the bottom of the pipe and preferably to the inside of the vertical plane X-X. With this construction the distance a is somewhat less than the outside diameter of the pipe and as a result the anchors will be clamped to the pipe so that they will remain attached even if the strap 16 were removed. Before the anchor can be removed, the parts have to be turned to the position shown in Figure 5, which requires a slight flexing of the anchor.

The modification shown in Figures 4 and 5 is not necessary for ordinary canvas furniture of the hammock type, but may be desirable for furniture and other structures having a more permanent assembly.

It is to be understood from the above description that the apertures [4 can be positioned almost any place along the lower righthand quadrant of the pipe shown to the right in Figure 2. It should preferably be below the horizontal plane and may be positioned to the left of the vertical plane as shown in Figure 4 in extreme cases where the supporting member is to'be more permanently attached.

It will be obvious from the above description,

taken in connection with the drawing, that when a supporting member is provided with anchors of the type shown and described, it can be quite readily applied to the frame or removed therefrom with the result that it can be removed when storms are approaching or during the seasons when this particular furniture is not used.

Having described the invention what is claimed as new is:

An article of furniture formed to support an occupant in a condition of repose andcomprising a frame having an opening defined in part by a pair of similar, parallel, spaced apart members, annular in cross section and forming the sides of the frame, a flexible sheet extending substantially from one member to the other, and means removably supporting said sheet in position to support the body of said occupant; each of said members being provided with a series of apertures with each aperture of one series in alignapertures, the straps being of such length as to provide just sufficient slack therein to permit each anchor element to be removed from the frame member engaged thereby by a swinging movement in the proper direction to break the engagement between such element and such member.
